IMPROVEMENT IN WATER-CLOSETS.

Specification forming part of Letters Patent No. 136,199, dated February25, 1873.

To all whom t may concern:

Be it known that I, JAMES ALBEE, of Chelsea, of the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Water-Closets and do hereby declare the same to be fully described inthc following speciiication and represented in the accompanying drawing,of which- Figure l is a horizontal section, and Figs. 2 and 3 arevertical and transverse sections, of a water-closet with my improvementor invention. Fig.A 4 is a top view, and Fig. 5 a

transverse section, of the annular Ventilator which circumscribes thetop ofthe pan.

The purpose of my invention is to ventilate the pau in order to preventthe escape through the seat-opening of any o'ensive odor after a depositof feces in the pan.

To accomplish this I make use of a hollow annulus, A, formed with agroove or channel, a, to receive, rest upon, and iit to the upper edgeof the pan B, and I provide such annulus, on its inner periphery, with aseries of holes, as shown at b, and, on its outer periphery, withaneduct, c, to lead into a pipe or tlue for the discharge of the vitiatedair. The seat is shown iat C as constructed with a seathole, d, of 'aIdiameter less than the inner diameter of the annular ventilator, allbeing as shown.

In practice theventilator made and arranged with a water-closet pan andseat in manner as described has been found to be highly effective, andto thoroughly prevent the escape through the seat of any offensive odor.Being arranged on the top of the pan and immediately underneath theseat, and having its inducts disposed jaround the seat -opening, itreadily intercepts and carries oft' any gases from deposits in the pan.The openings into the ventilators being arranged in close proximity tothe position Where the air in the pan comes in contact with theposterior of a party 'While sitting upon the seat, readily receiveV thewarmed air, which, passing through the i.

ventilator, induces a corresponding influx of cooler air downwardthrough the seat, thereby preventing the escape of odor upward throughthe seat.

I claim- The annular ventilator, substantially as described, and also ascombined and arranged with the water-closet pan, or with such and theseat, essentially as specified.
